"This is a queer turn to affairs," thought Nat, as he awaited the arrival of Captain Turton. "I never thought a thing about not having a license, when I steered the boat, and I don't believe Mr. Weatherby did either. I suppose I did wrong, but it was unintentional, and I don't see what else I could have done under the circumstances.

"But I'll have a chance at Bumstead now. As soon as I get out of here I'll cause his arrest. Hold on, though, maybe I'll not get out of here. I wonder what the punishment is for piloting a boat without a license?"

This was another phase of the queer affair. He realized if he was held on the charge, he would have no chance to make an accusation against the rascally mate.

"I know what I'll do," said Nat to himself, while he anxiously waited. "If Bumstead comes here I'll tell Captain Turton to go out and get a policeman. Then I can make a new complaint, charge Bumstead with keeping money belonging to me, and he'll be arrested. That's what I'll do."

While Nat sat in the office of the harbor master, he listened to several cases that were being disposed of. Captains of tugs and other boats were arraigned on charges of violating rules of the harbor; such as displaying wrong lights, crossing the course of other boats at the improper time, failing to give warning signals, colliding with other craft, or not filing the proper reports.

Some of the men were fined, others were suspended for a certain length of time, and one or two had their licenses revoked.

"I wonder what he'll do to me?" thought Nat. "There doesn't seem to be any case just like mine."

He was interrupted in his musing by the entrance of Captain Turton.

"What's this I hear?" asked the commander wonderingly, after he had greeted his young pilot. "Are you in trouble, Nat?"

"It seems so," and the boy told the circumstances.
